RBBB (Really Bare Bones Board)

Description

The Really Bare Bones Board (RBBB) is a mini board designed for those experimental applications that require small processors, such as wearable computing, near space experiments, toy prototyping, artist’s projects or any use for a fairly small, low-cost microcontroller.

It’s one of the smallest and lowest-cost Arduino-compatible boards available right now. You can build a RBBB in under half an hour, even as a beginner. The pin labels on version B2 are now between the pins, similar to the Arduino Nano.
